OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Scarifier blade for SB.

I have seen somewhere a scarifier blade that bolts in for the Scott Bonnar cylinder mowers, but can't remember where (cylinder and base plate come out and scarifier bolts in where cylinder went). Has anyone else seen this or know where I can get one?
